In a d.c current, the power is the product of voltage and current. This relationship does not always apply to effective(r.m.s) values in an a.c circuit. Explain the reason for this.
2 5386In a d.c circuit, if current and resistance are known, power (P=I*I*R) can be determined. This relationship also applied to an a.c circuit. Comment the reason for this.
